Hope for overacheiver?

I recommend seeking out avenues for increasing throwing velocity. It may be possible to improve his throwing mechanics and arm strength. If he gets to 80+ he could pitch for a high end academic D3. If you're considering northeast colleges check out the D3 NESCAC programs. These schools are sometimes called Small Ivies. 

Outstanding advice.

Welcome to the hsbbweb!

The IVIE's are D1 programs so no way does he ever get an offer there based on baseball.

There are high school teams out there were 75 mph will not get a look let alone these types of schools.  Maybe encourage him to ace his SAT's and ACT's and get into the IVY that way.  Many of the D3's as RJM mentioned have IVY-like credentials so that might be a path with an increase in velocity.

Husky Huskie Dad,

Again, welcome to HSBBWeb.   I think RJM and CD have given you some great advice.  Possibly seek out a reputable pitching coach in your area to work with him on arm strength.  If he has the grades and board scores to get into Ivy or NESCAC schools, then trying to get his mph up may be  the best path.  I've watched the Ivy League very closely the last few years and I've seen the pitching velocity go up a few mphs across the board for starters, middle relief and especially closers.  It has become a very pitching dominant league.   You may want to do some of your own research on pitching velocity in the Ivy League if you are interested.

Here's a thought.....There is one pitcher that I know that was recruited because he was able to convince the coaches he could change his arm slot (submariner) to be successful in giving the hitters a much different look.  He is a very smart kid, so he had the academics covered.  He was not a hard overhand thrower in high school, but he did change his arm slot to earn a spot on the college team, and has worked hard to learn more pitches this year.  That may be something else you consider if your son wants to become a role player or specialist in an Ivy or other school.  Just a thought to consider.

"There is one pitcher that I know that was recruited because he was able to convince the coaches he could change his arm slot (submariner) to be successful in giving the hitters a much different look."

It seems like every team in the ACC had a submariner when my son played.  On my son's team, the submariner was the closer, got drafted and is doing well.  He topped out at 82, 

Great point about the submariner!!!

There are a couple of submariner's at my son's former college right now and they are both All-Americans.  I know one of them cruises at about 78 mph and the release point of his pitches are about 6 inches off the ground.  They are affectionately known as knuckle-scrappers and they can get recruited at big time schools including IVIE's. 

Great advice.  Thank you.

I have seen coaching systems the promised increased mph, but I always assumed they were a scam.  To be clear, I believe a coach could take him from 75 to 77 or 78.  But to 82?  I assumed that wasn't possible.

He still has a boy's build, not a man's.  Do you think he will pick up mph as he fills in?  Or is that settled as soon as he gets to his full height (I'm only 5'8", so he is already way taller than me, and maybe near his top)

I would like to mention something about arm strength. My son has been involved with a program called Combat Pitching. It is a program that he does in the winter during his off-season for 6 weeks. He goes 2 days a week which last 3 hours per session. It involves medicine balls, ropes, hula hoops, weighted balls, high boxes for vertical jumping, bands, and core work. All these things are incorporated into a workout that improves core strength and arm strength .My son has done this program since he was 12 and now he is a soph. His velocity has increased from high 70's to 89-90. Now, he does a lot of extra work on his own. He has a pitching coach and a weight traning coach specifically for pitching. He is a hard worker but I truly believe this conditioning has kept him not only healthy but increased his arm strength and stamina.
